13. The system of claim 10 , wherein the system is further configured to analyze and correct font information prior to comparison of the font format of the determined font data to the predetermined common font data format.

14. The system of claim 10 , the system is further configured to determine if the font data in the predetermined common font data format comprises hinting information and in response to a detection of absence of hinting information to determine the hinting information to the font data in the predetermined common font data format prior to creating the plurality of document-specific web font files.

15. The system of claim 14 , the system is further configured to add the hinting information to the font data in the predetermined common font data format in response to the determination of the hinting information.

16. The system of claim 14 , wherein the system is configured to determine the hinting information by performing at least one heuristic operation.
